GRATER.

SPECIFICATION forming part of Letters Patent No. 470,807, dated March 15, 1892. Application filed July 8, 1891. Serial No. 398,827. (No model.)

To aZZ whom it may concern.-

Be it known that I, ISAAC S. LAUBAOK, a citizen of the United States, residing in the city, county, and State of N ewYork, have invented certain new and useful Improvements in Graters, of which the following is a specification.

This invention relates especially to culinary graters, such as are used for grating nutmegs, horse-radish, potatoes, and other substances.

The object of the invention is to provide an improved grater of this general character which shall be simple in construction, compact in form, which can be easily operated, and can be manufactured at slight expense.

To this end in carrying out my invention in its preferred form I provide an endless guideway and a substantially disk-like grating-surface and aholder for retaining the ma terial to be grated in contact with said surface and movably connected to said guideway, whereby when the holder is moved over the grating-surface its contents are grated thereon. By this construction it is possible to use a continuous and substantiallyflat grating-surface of a shape best adapted to the most convenient movements of the hand of the person operating the grater.

In the accompanying drawings, which illustrate the preferred form of myinvention, Figure 1 is an axial cross-section of a grater, and Fig. 2 is a side elevation thereof, being partly broken away at the right-hand side. Fig. 3 is a section of the disks, and Fig. 4 is a section of a modification.

Referring to the drawings, let A represent the holder for the materials to be grated, B the grating-surface, and C an endless track or guideway surrounding the latter.

D is a box or receptacle for the grated material, and E is a handle for the grater proper.

The holder A is preferably constructed of tubular form, being of Sufficient size to receive the largest material'to be grated. Preferably it is constructed with a cylindrical body portion a, an enlarged swell or annular boss I) at its end adjacent to the grating-surface, and with a screw-thread c at its opposite end. A cap F is preferably provided for closing the outer end of the holder A, which cap is provided with a screw-thread d by preference for engagement with the screw-thread c ofthe holder.

G represents a nutmeg Within the holder, which is preferably pressed into contact with the grating-surface by means of a spring H. This spring Ellis preferably a spirally-coiled spring, securec at its upper and wide end to the cap F and at its contracted lower end toa plate e, which rests against the nutmeg or other material G. The spring H is constructed to force the presser-plate 6 into close proximity with the grating-surface B when the spring is fully distended, whereby the material G will be completely grated, and thesaid spring is constructed, when completely compressed, to lie flat against the top of the cap F, whereby the holder A can be completely filled with material to be grated.

The guideway C is preferably employed for connecting the holder A to the grating-surface B. It may be of any construction which will serve this purpose; but I prefer to construct it of overhanging tracks or flanges f f, carried by the grating-surface and con struct'ed to engage the enlargement or annular boss 1), formed on the end of the holder A. The guideway 0 thus forms a complete groove or track following the path of the gratingsurface B, so that as the holder A is moved in the guidewayB it will traverse the surface B in a continuous path.

The grater proper is preferably constructed of a disk of sheet metal, on which is formed the grating-surface 13, another disk stamped to form the box D, and a small disk I, the three being secured in the position shown in Fig. l in any suitable manner-as, for example, by one or more screws g passing through the several pieces and engaging the handle E. The disk for the grating-surface is preferably stamped with a raised central portion h, an annular curved portion 2', a flat portion j surrounding the latter, a slightlydepressed portion is, punctured to constitute an annular grating-surface, a flat portion j surrounding the outer edge of the portion is, and an outer curved flange f, constituting the outer portion of the guideway O. The disk I is preferably a flat disk, having a curved annular flange f, which, when the disk is secured against the raised portion 72, of the adjacent disk, constitutes the inner portion of the guideway C. The parts j and j at the opposite sides of the grating-surface B constitute runners, on which the lower edge of the embossment b of the holder A rests as the holder is moved around the grating-surface. The disk constituting the receptacle D is preferably stamped out with a central raised portion Z, constructed to fit within the portion h of the adjacent disk, and exteriorly of the portion Z it is constructed with a depressed annular portion on, which terminates in an annular flange n, extendinginto contact with the outer edge of the adjacent disk, whereby as the disks are clamped in place an annular box or receptacle is formed beneath the gratingsurface. The grated material falls into this box or receptable D, from which it is removed through a slot or aperture 0.

The handle E may be of any construction; but I prefer to construct it with a large boss 7, fitting within the portion Z of the disk at the back of the grater.

In the construction described the cap F will be removed from the holder A when it is desired to use the grater, and the material ill be placed in the holder, whereupon the .cap will be screwed onto the holder until the spring II is compressed to give the desired tension against the material G. The operator will then grasp the handle E with one hand and the holder A with the other and will move the latter rapidly around in the guideway 0 over the grating-surface, continuing the movement until the desired amount of material has been grated or until the material within the holder is completely grated and the presser-plate 6 comes in contact with the grating-surface.

It will be seen that my invention provides a grater of simple, durable, and compact eonstruetion, which can be made very economically and usedwith great facility. Itpermits a circular or elliptical movement of the holder A, which is particularly convenient to the user in operating the grater and affords an extensive gratin g-surfaee, throughout all portions of which the grating operation is substantially uniform. The material within the holder A tends to maintain the same position therein, so that as the holder is moved around the grater that portion of the material which is nearest the inner edge of the grating-surface at one position of the holder is nearest the outer edge of the gratin surface at a diametrieally-opposite position, thus causing the material to be uniformly grated on all sides.

The grater can be readily cleaned, and

when desired the various pieces can be separated in order to get access to the interior or replace any damaged member.

It will be understood that my invention may be variously modified and used either in whole or in part in graters of this class without departing from its essential features. I have not deemed it necessary to illustrate such modifications or applications of my invention, since these will be apparent to those skilled in the art, except that shown in Fig. 5, wherein the holder A is cup-shaped, having the spring H and adapted to beheld freely in one hand of the user and pressed against the grater, while the grater-disk is rotary, having a crank-handle E and mounted on hearing q, secured to a table or other support. Arecept-aole Dis shown as fastened on the bearing (1 behind the grater to receive the grated material.

Instead of a guideway to which the holder A is connected, a flange O at the outer edge of the grater-disk is substituted to guide the holder.

hat I claim is, in a grater, the followingdefined novel features and combinations, substantially as hereinbefore set forth, namely:

1. In a grater, the combination, with a holder for retaining the material to be grated and a grating-surface, of an endless guideway to which said holder is movably connected.

2. In a grater, the combination, with a stationary disk-shaped grating-surface and a movable holder for the material to be grated, of a disk-shaped receptacle for the grated material, secured rigidly to and inclosing the back of said grating-surface in the form of an endless trough.

In a grater, the combination, with a diskshaped grating-surface and a holder l'or the material to be grated, ot' a handle rigidly secured to said grating-surface, whereby the latter maybe supported in one hand of the operator, while with the other said holder may be moved over said surface.

l. In a grater, the combination, with a holder for the material to be grated, of the disk-shaped grating-surface having the upturned outer edgef and the annular portions 1 jj, as and for the purpose set forth.

5. In a grater, the combination, with a holder having an enlarged end I), of the guideway 0, engaging said enlarged end, and the grating-surface 13, adjacent to said guideway, as and for the purposes set forth.

6. In a grater, the combination, with a holder for the material to be grated, of the grating-disk B, the disk I, and the receptacle D, as and for the purpose set forth.

7. In a grater, a disk-shaped gratin -surface adapted to be held in one hand, in combination with a holder for retaining the material to be grated against said surface, adapted to be held in the other hand and when so held to be moved in a substantially circular path over said surface, whereby in its circuit said holder maintains a substantially non-rotative position relatively to itself while traversing said path, thereby presenting that ICC my name in the presence of two subscribing part of the material being grated at the outer side of the grating-surface at one portion of Witnesses. its circuit at the inner side of said surface during a diametrically-opposite portion of its ISAAC LAUBAGK' 5 circuit, substantially as and for the purpose Witnesses:
